American actor and voice artist, known as the Crypt Keeper in Tales from the Crypt, who played Gar, the thief who steals the Doctor's mobile emitter, in Voyager's Critical Care.
John Kassir is an American actor, comedian and voice performer, most widely recognised as the cackling voice of the Crypt Keeper in Tales from the Crypt.
In the seventh-season Voyager episode Critical Care he played Gar, a smooth-talking trader who makes off with the Doctor's mobile emitter and sells the Doctor's programme to a hospital ship where treatment is rationed by social worth.
While the Doctor fights that system, Voyager's crew follow a chain of Gar's cheated customers to track him down. Once he is caught, Neelix and Tuvok get the truth out of him with a doctored meal and the threat of a mind meld.
